Also, could you provide a snippet ?

Kind regards,

hi,

i tried following task
i used the annotation demo
i added a Mousup Event to the gdviewer1 component

following code tries to add a lineannotation to the loaded pdf
after saving the pdf the annotation is added but the line is not at the right position in the pdf.

Do i have a wrong idea of how it should work?

i want have the marker in the pdf and on mouseover or click i want to see the annotationtext.

Code: Select all

// check a rectangle has been drawn
            if (GdViewer1.IsRect())
            {
                int t_left = 0;
                int t_top = 0;
                int t_width = 0;
                int t_height = 0;

                // get the co-ordinates / size of the drawn area
                GdViewer1.GetRectCoordinatesOnDocument(ref t_left, ref t_top, ref t_width, ref t_height);
                int regionID = GdViewer1.AddRegion("myRegion'", t_left, t_top + t_height, t_width, 3, ForegroundMixMode.ForegroundMixModeMASKPEN, GdViewer1.ARGB(0,0,255,255));

                float n_left = GdViewer1.GetRegionLeft(regionID);
                float n_top = GdViewer1.GetRegionTop(regionID);
                float n_width = GdViewer1.GetRegionWidth(regionID);
                float n_height = GdViewer1.GetRegionHeight(regionID);

                pdf.AddLineAnnotation(n_left,
                    n_top,
                    n_left + n_width,
                    n_top + n_height,
                    "Comment",
                    "myFirstComment",
                    PdfAnnotationLineEndingStyle.PdfAnnotationLineEndingStyleOpenArrow,
                    PdfAnnotationLineEndingStyle.PdfAnnotationLineEndingStyleClosedArrow,
                    false,
                    n_width,
                    PdfAnnotationBorderStyle.PdfAnnotationBorderStyleUnderline,
                    0,
                    0,
                    1,
                    255, 0, 0);

Hi,

I think you have a coordinates space issue.

Could you try this ? (not tested form my side, I have to go).

Code: Select all

// check a rectangle has been drawn
            if (GdViewer1.IsRect())
            {
                float t_left = 0;
                float t_top = 0;
                float t_width = 0;
                float t_height = 0;

                // get the co-ordinates / size of the drawn area
                GdViewer1.GetRectCoordinatesOnDocumentInches(ref t_left, ref t_top, ref t_width, ref t_height);

                pdf.SetMeasurementUnit(PdfMeasurementUnit.PdfMeasurementUnitInch);
                pdf.AddLineAnnotation(n_left,
                    n_top,
                    n_left + n_width,
                    n_top + n_height,
                    "Comment",
                    "myFirstComment",
                    PdfAnnotationLineEndingStyle.PdfAnnotationLineEndingStyleOpenArrow,
                    PdfAnnotationLineEndingStyle.PdfAnnotationLineEndingStyleClosedArrow,
                    false,
                    n_width,
                    PdfAnnotationBorderStyle.PdfAnnotationBorderStyleUnderline,
                    0,
                    0,
                    1,
                    255, 0, 0);

Kind regards,

Loïc

Hi,

Well I finally tried. Here a snippet that should work:

Code: Select all

// check a rectangle has been drawn
            if (GdViewer1.IsRect())
            {
                float t_left = 0;
                float t_top = 0;
                float t_width = 0;
                float t_height = 0;

                // get the co-ordinates / size of the drawn area
                GdViewer1.GetRectCoordinatesOnDocumentInches(ref t_left, ref t_top, ref t_width, ref t_height);

                pdf.SetMeasurementUnit(PdfMeasurementUnit.PdfMeasurementUnitInch);
                pdf.SetOrigin(PdfOrigin.PdfOriginTopLeft);
                      m_pdf.AddLineAnnotation(l, t, l + w, t + h, "titre", "content", PdfAnnotationLineEndingStyle.PdfAnnotationLineEndingStyleCircle, PdfAnnotationLineEndingStyle.PdfAnnotationLineEndingStyleCircle, True, 0.01, PdfAnnotationBorderStyle.PdfAnnotationBorderStyleSolid, 0, 0, 1, 255, 0, 0);

Note: you had to define the Origin coordinate. By default in PDF it is bottom-left when in GdPicture Image it is top-left

i have downloaded the latest version 8.4
i did a change on the annotation example as i added a function (followint code)

private void tsAnnotation_Click(object sender, EventArgs e)
{
// check a rectangle has been drawn
if (GdViewer1.IsRect())
{
float t_left = 0;
float t_top = 0;
float t_width = 0;
float t_height = 0;

// get the co-ordinates / size of the drawn area
GdViewer1.GetRectCoordinatesOnDocumentInches(ref t_left, ref t_top, ref t_width, ref t_height);

pdf.SetMeasurementUnit(PdfMeasurementUnit.PdfMeasurementUnitInch);
pdf.SetOrigin(PdfOrigin.PdfOriginTopLeft);

int annot = pdf.AddLineAnnotation(
t_left,
t_top + t_height,
t_left + t_width,
t_top + t_height,
"mein Kommentar",
"mein erster Kommentar",
PdfAnnotationLineEndingStyle.PdfAnnotationLineEndingStyleCircle,
PdfAnnotationLineEndingStyle.PdfAnnotationLineEndingStyleCircle,
false,
1 / 100,
PdfAnnotationBorderStyle.PdfAnnotationBorderStyleSolid,
0,
0,
1,
255,
0,
0);
GdViewer1.Redraw();
MessageBox.Show(string.Format("annot nr: {0}; anz: {1}", annot, pdf.GetAnnotationCount()));
}

this code is working as it adds an annotation with text and a line without circles.

i save the file in a new pdf and view it with adobe reader, foxit reader where i can see the line and the circles.
if i view it wth gdviewer1.displayfromGDPicturePdf(pdf) i see only the line without the circles.

Another question is: how can i select the annotation within the gdviewer as AnnontationSelected ist not fired. Do i have to check it by myself with mousemove events checking against the properties of the annotations (rectangles)

i tried to Attach the pdf which is not working.

btw. if i view the pdf in foxit and save it again / the circles are shown in gdviewer on reviewing the pdf
